Abstract

The invention relates to the mining industry and m. used for mechanized excavation of steep seams. The goal is to increase the patency of the gateway fastening. The mating support includes arched sections 1 of the support and crust sections 15, including movement jacks (DPs) and associated with each other by means of pivotally connected intermediate bases 19. The front base of which is made with a share 22 attached to the DP core section. Between themselves and the base of the arch section 1, the intermediate bases 19 are connected by means of sheets 27 fixed on one of the adjacent bases 19. The width of the sheets decreases from the front intermediate base to the base of the arch section 1 of the support. On the intermediate bases 19, a loading crane 7 and a loading crane with elongated beams are mounted. Coal Falls on the cranes and is transported to the monorail 9. 7 Il. S

The invention relates to the mining industry and can be used for mechanized excavation of steep layers.

The purpose of the invention is to reinforce the cross-country support of the gateway.

FIG. Figure 1 shows the mating support, general view; in fig. 2 - In order to prevent coal and rock from spilling in places where the drift rails are removed, the loaders on the length of intermediate bases on the side of the drift are provided with elongated ones. sides 25, at the ends of which are fixed rubber segments 26.

To prevent spillage

cut A-A in FIG. one; in fig. 3 - section (O coal and rocks in the gaps between PromeB-B in Fig. 1; Fig. 4 - Section B-B in Fig. 1; Fig. 5 - Section G-D in Fig. 1; Fig. 6 is a view of D-D in Fig. 5; in Fig. 7, a resharter of a reloader with an elongated board, cross section.

The mating support consists of an arched section 1 of the support, mounted on the interface of a diagonal clearing

The commanding bases and the base of the arch section of the support are covered with sheets 27, which are fastened on one of the adjacent bases, the width of which 15 decreases from the front intermediate base to the base of the arch section of the support.

The position of the intermediate base 28 in the curved c. horizontal 2, which at the same time is the 20th plane of the drift plane, shows puncture niche 3 for a notch in a combine. The haulage 4 is fastened with a metal support 5.

In the arched section of the lining there is a lee 6 for passing the beaten off in the clearing

I coal on a loading crane 1, kon1

The salt of which is suspended on a chain x 8 to the 1-monorail road 9, as well as the ItO window, which serves as an emergency exit | from the mechanized lining in the clearing | bottom of the mate. {The arch section of the mating consists of a base 11, on which hydroracks 12 are mounted, supporting semi-arches 13, connected by | above by a hinge 14.

To move the lining mate, on the drift is the root section 15, I which consists of side spacing skis 16, transverse jacks 17 and movable jacks 18. An intermediate base 19, connected by hinges 20 with a base, is fixed between the arched support section and the crust section and is supported by another front intermediate base 21, which is provided with a ploughshare 22 in front for stripping the roadway liner and is attached to the main section jacks. I

To clean the coal in front of the arched

A support section 23 is installed in the support section and inside it on intermediate bases; its bypass head with the tray 24 for overloading coal onto the main loading crane is fixed inside the support support.

The commanding bases and the base of the arch section of the support are covered with sheets 27, which are fastened on one of the adjacent bases, the width of which decreases from the front intermediate base to the base of the arch section of the support.

The support works as follows.

In the initial position, the arch section of the mating 1 is located at the junction of the diagonal cleansing hole 2, which is both the harvester's niche 3, and the haulage drift 4, where the metal lining 5 is removed and the exposed side walls are supported. wives The hatch 6 for passing the coal recovered in the bottomhole is located opposite the machine road, where the coal is excavated, and the emergency exit window 10 is located against the end section of the powered support in the clearing bottom.

When coal is excavated in a niche for a notch of a combine using a jackhammer, coal enters the material handler 7 installed on the intermediate bases 19 and 21, the coal goes to the material handlers 7 and 23, while the material loader transports the corner to the arched support section and through the tray 24 it overloads it to the main reloader, which transports coal along the reloader's boom suspended on chains 8 to the monorail road 9. Part of the coal from the recess, as well as when removing the liner Vani, delayed sheets 27 which are attached on one of the adjacent base, and then falls on the conveyors.

Movement of support mate on the drift is carried out as follows. With removal of lateral

jacks with the help of motion jacks 18 are made to move the crust section 15 and strut it with drift frames. In advance of the arched section of the support mating, the frame of the roof support, and then thrusting the hydraulic rails 12, in this case, two semi-armatures 13 connected by the hinge 14 are lowered, the coupling is attached to the main device by means of hinges that are connected with plowshare 22, stripping the base of the drift from the coal.

The cycle for advancing the mate is repeated after the execution of the technological cycle in the clearing face.
